NllED STATES ALEXANDRE VINOI-ION, OF ROUBAIX, FRANCE.

CARDINGMACHINE.

SPECIFICATION forming part of Letters Patent No. 621,183, dated March 14, 1899.

Application filed November 6, 1896. Serial No. 611,226. (No model.)

To aZZ whom it may concern.-

Be it known that I, ALEXANDRE VINOHON, manufacturer, manager of La Socit du Peignage de lEpeule, of Roubaix, Department du Nord, in the Republic of France, have invented new and useful Improvements in and Connected with Oarding-Machines, (for which I have obtained Letters Patent of France for fifteen years, dated October 10, 1895, No. 250,885; Germany, dated November 2, 1895, No. 89,790; England, dated October 24, 1895, No. 20,065, and Belgium, dated October 12, 1895, No. 117,853,) of which the following is a full and exact description, reference being made to the accompanying drawings.

Thisinvention relates to improvements in and connected with carding-engines.

It has hitherto been customary in all carding-engines to clean the wool on the pickerroller (roule tabosse) or on the adjacent rollers, which are furnished with teeth. By this method, however, only an imperfect result is obtained, for two reasons-first, because the wool is very slightly divided on the said picker-roller, which forms the first drawingroller of the carding-engine, and because it is there entangled by large fibers, so that the burs and other impurities remain hidden and retained in the wool, whereby the pickers are unable to seize and remove them, and, sec ondly, because the roller has a very rough surface, on which the picker can never ob tain a hold on the burs and other impurities to remove them. To overcome these two defects, I provide on the carding-engine, directly after the picker-roller, a cleaning arrangement, the chief feature of which is a roller, on the periphery of which are arranged strips provided longitudinally with serrations or teeth on both edges and having a smooth part adjacent to the toothed portion, the said smooth part being arranged transversely on the roller. The roller seizes the wool, which is suitably fed to it, draws it, and fixes it in the teeth of its combs. The fibers open out, thereby exposing the burs and other impurities, which one or more pickers easily remove without injury to the fiber.

The same device can be employed with simple or with double cardingengines. When it is conducted to the second main cardingcylinder.

The use of my device in combination with a carding-engine produces a carded wool which is perfectly cleaned and which after combing forms a material much cleaner than that produced with machines at present in use.

To enable my invention to be fully understood, I will describe it by reference to the accompanying drawings, in which- .Figure 1 is a diagrammatic view showing the application of my device to a double carding-engine. Fig. 2 is a vertical section of a portion of my cleaning device on the line 2 2 of Fig. 3. Fig. 3 is a front elevation of the same, showing the arrangement of the toothed strips. Figs. 1 and 5 are detail views of the strip shown in Fig. 3, and Fig. 6 is a diagrammatic view illustrating the application to my cleaning-roller of a fixed metal strip in combination with a brush.

In carrying out my invention the wool is spread on an endless band or carrier a, seized by two pairs of feed-rollers b b, and fed to the picker-cylinder c, which draws it out and enables the first picker h to remove the larger burs'and other impurities. The wool. then passes to my device, which comprises the toothed roller d, and between this roller and the picker-cylinder c a brush f and a cardingroller g. The brush f and the carding-roller 9 both have the same circumferential velocity, which is greater than that of the pickerrylinder 0, whereby they detach the wool from the latter and maintain it between them, while the toothed roller d, which has a circumferential velocity greater than that of the brush f and the carding-roller g, seizes the wool, draws it and fixes'it in the teeth of the strips lin such a way that the fibers spread themselves out on the smooth parts of the said roller adjacent to the teeth, whereby the burs and other impurities are forced to the top and can be easily removed by pickers m and thrown into a suitable receptacle n. The wool is then removed from the toothed roller (Z by an ordinary roller p, which passes it to the main carding-cylinder T.

The foregoing description refers to the application of the device to a simple cardingengine.

Fig. 1 shows the application of my invention to a double carding-engine. In this case the wool is removed from the doffing-cylinder g by a brush f and a carding-rollerg, similar to f and g, and is then passed to the second toothed roller 61, where it is operated on by one or more pickers m. The roller 1) then removes the wool from the toothed roller (1 and delivers it quitecleaned to the second main carding-cylinder T. By this means a better result is obtained, although the employment of my device before the first main carding-cylinder is sufficient in most As heretofore stated,the longitudinal strips forming the peripheral surface of the toothed roller are provided with teeth on both edges. If the strips are provided with teeth on one edge only, spaces are left between the successive strips, the said spaces being formed by the space left between the consecutive teeth of each strip and the edge of the strip next it. To obviate this disadvantage, the spaces between the teeth of each strip are filled up as followsthat is to say, the back and the front of each strip are, as shown in Figs. 2 and 3, provided with teeth or serrations in such a manner that the teeth 1 on the rear edge of one strip lie between the teeth 2 on the front edge of theadjacent strip, the teeth of the two edges leaving between them a play or space of from seven to eight tenths of a millimeter. The front of the strips-that is to say, the front edge, having regard to the direction in which the roller rotates-is beveled or chamfered on its lower surface, so that the teeth formed on this edge seize the wool and comb it. The rear edge of each strip is, on'the contrary, left of the full thickness, so that the teeth formed on the said edge do not interfere with the work in any way, as they can neither seize nor retain the wool.

Fig. 6 is a diagrammatic sectional elevation of my cleaning device combined with a fixed strip 4 and a brush 5 for detaching the burs. The strip I and the brush 5 are designed to replace the picker m. (Shown in Fig. 1.) The said strip 4,which is about two millimeters in thickness, is attached to a support or ribbed cross-piece 6, so as to impart the necessary stiffness to it. The cross-piece or support 6 is placed and fixed upon the outside supports of the dotting-cylinder, and the strip 4 is arranged parallel to the generatrix of this cylinder, so that it can be adjusted as near as possible to the outer surface of the same.

If desired, the strip 4 can be arranged with its plane forming a tangent or secant to the outer surface of the doffing-cylinder. It will be obvious that the cylinder when rotating in the direction of the arrow 7, Fig. 6, causes the strip 4 to arrest the burs and other impurities, which are then removed by the brush 5.

It will also be obvious that my device can be applied to all types of carding-engines, both after the picker-roller and doffing-eylinder or after the picker-roller alone or even after the dotting-cylinder alone, as above described.

I claim 1. In a carding-engine, a carding or cleanin g roller provided with longitudinal grooves, the outer surface of the said roller being form ed of strips or combs provided with teeth I on their opposite edges projecting over the said grooves whereby the front teeth of one strip register with the spaces between the rear teeth of the adjacent strip, substantially as shown and described.

2. In a carding-engine, a bur-cleaning roller having longitudinal grooves formed in its periphery, and combs or strips forming the outer surface of the roller, the said ou er surface being concentric with the axis of the roller, the said strips having projecting teeth on their opposite edges, the teeth on the front edge being beveled or chamfered on their inner faces and registering with spaces between the rear teeth of the adjacent strip, substantially as described.

3. In aearding-engine,abur-cleaning roller provided with longitudinal grooves in its periphery, the outer surface of the said roller being formed of strips orcombs provided with teeth on their opposite edges projecting over the said grooves, whereby the front teeth of one strip register with the spaces between the rear teeth of the adjacent strip, the said front teeth being beveled or chamfered on their inner faces, substantially as described.

4. In a carding-engine, a picker-cylinder,

a carding-cylinder, a carding or bur-cleaning roller located between the picker-cylinder and the carding-cylinder and provided with longitudinal peripheral grooves, the said cleaning-roller having its outer cylindrical surface formed by strips toothed on their opposite edges, the teeth projecting over the said grooves, and the front teeth of one strip registering with the spaces between the rear teeth of the adjacent strip, and means for detachin g the wool from the picker-cylinder and presenting it to the said cleaning-roller, substantially as shown and described.

5. 111 a carding-engine, the combination with a picker cylinder or roller and means for feeding the wool thereto, of a carding or bur-cleaning roller provided with a series of longitudinal grooves formed in its periphery, the outer surface of the said roller being formed by strips toothed on their opposite edges and projecting over the said grooves,- the front teeth of one strip registering with the rear teeth of the adjacent strip, means for detaching the wool from the picker-cylinder and presenting it to the said cleaningroller, and means located adjacent to the periphery of the said bur-cleaning roller for arresting the burs and removing the same, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.
